Yeah WhiteNoise, it was so embarrassing at the time though, especially as there were two of us doing the CBT and the other guy (aged 17 and I'm 30) had no problem with it at all ...
Turns out he had quite a bit of experience with off-road motorcycles though which made me feel a little better.
My advice for the CBT would be:
1. Stay Calm and listen carefully
2. Don't worry if you can't do something immediately, it may take a few goes (like my center stand problem lol

)
3. Remember your highway code for the Q&A bit, especially different crossings
4. Have fun and enjoy it!
